: good stuff!
so whats up with the pulley then?
theres always a way of getting round special tools 
The pulley has seized, I don't fully understand how they work but it seems it doesn't always engage witht he alternator or something. Anyhoo there is clearly no way round this special tool as it has to lock two bits from spinning while undoing something else. Not to worry though as the tool is pretty cheap and might in come in handy on my Dad's Bora as these pulleys seizing is very common.
THe garage reckon it'sll be fine for a while but I'm gonna see if I can get all the bits to do it on Saturday along with a Fuel filter, Oil Filter and Oil Change.
